Is PASSIVE CROSSOVER pointless if YOUR audio system has a DSP?

Whenever I use a Passive Crossover for a set of component speakers on a car audio system that has a DSP the question comes up: "Why use a passive crossover with a Digital Signal Processor?" In this video I explain why one might be needed depending on the design of your car audio system and what tweeters, midrange and subwoofers are part of the sound system.

I really hate to say this but these videos are obviously for professional installers and not for your average Joe. I was really hoping I could get some more insight about installing my system but now I'm more confused than I was before I purchased my system. At any rate, I'm not criticizing you. I'm just more disappointed in myself. Hopefully I can find some videos that speak in simpler terms for us dummies who just want good sound in our cars system. Sorry to sound so negative. I'm sure you're a great guy who loves his trade.

You’re funny. But I agree.

[@travisjacobson682]

This comment is a year old, but I just read it today and I feel ya. When it comes to upgrading an audio system, the number of options and levels of complexity can be overwhelming. He is obviously a professional and his videos (this one in particular) can go pretty far into the weeds. However, there is no need to dive headfirst into the cutting edge. If you're looking to improve your system, I would recommend starting by replacing the factory speakers in the factory locations (I strongly recommend using Crutchfield because they will confirm whether or not speakers will fit your factory locations and they will provide all the necessary equipment for ease of install). I would also like to emphasize the importance of a good install. Cheaper speakers with proper installation (e.g. a secure mount and application of sound deadening in the doors) will sound better than expensive speakers with a poor installation. If you're not satisfied with that upgrade, add an amplifier to give the aftermarket speakers more juice. You can find a 50W RMS x 4 channel amp for $100-200. For a little bit more, something like the Kicker Key 200.4 provides that power with built-in automatic DSP. The next logical step IMO would be a subwoofer (some would argue to add a sub to your factory system as a first step). With audio, you can spend as much or as little as you want. At a certain point, you run into diminishing returns, where you might need to spend a lot more for an incremental benefit. My point is that you don't need to try to get the perfect system on your first try. Nearly every upgrade can be done piece-wise, and you can re-evaluate your satisfaction with the system after every step. Try the basic upgrades before you start down the rabbit hole of active crossovers, upgrading your alternator to add thousands of watts of power delivery, custom speaker pods/mounting locations, etc. Baby steps, my friend.

[@madhatterstunts]

@car audio fabrication So is it still beneficial to use a crossover on a 6ch amp?

[@Technotranceism]

I'm not sure how simply adding a passive crossover, is going to make any difference in channels for a component set. Even without the passive crossover, the woofer and tweeter can still function on 1 channel, albeit not recommended without the crossover filtering lower frequencies from playing thru the tweeter. Unless the passive crossover is changing the load rating between the component and amplifier, than it's really only a filter than.

[@iamjackalope]

I will add a couple of things worth mentioning that weren't talked about in the video when using passive networks down stream from active networks, weather they are active electronic crossovers or DSP. First off one needs to be knowledgeable about the passive network they are using. Is it Link-Riley, Butterworth, Bessal or possibly an elliptical cross over? What order is it? Second, third or forth? What's the roll off 12, 18, 24 db? These things are important to know because any frequency attenuation that is done with the cross over in DSP will change the behavior of the passive cross over. Of course there is nothing stopping one from mixing different types of cross overs in the same network . You are quite able to put a second order LR high pass x-over right next to a third order Butterworth low pass x-over in a band pass network if you like but your mileage may very. So it's important to know what your passive networks are so you can match them in the DSP or active network. You must remember that any frequency attenuation done with the DSP will add to the passive network so if you start with a second order LR in DSP and the passive x-over is also a second order LR what you will end up with is a forth order 24db LR x-over that may or may not exhibit phase issues. In this case sometimes it is best to not assign a x-over in DSP for those front two channels and leave that to the passive network and just use the DSP to EQ the channels and for time alignment. These issues are more prevalent I think with active electronic x-overs then they are with DSP but they can still exist. If the passive network happens to be elliptical combined with DSP you might find yourself dealing with some wonky phase coherence between the tweeter and the woofer especially if they are spaced far apart in a two way component set and in a three way component set those issues can become even more pronounced and hard to fix. There are many different choices we can make when deciding how we will ultimately end up using the sound equipment that we have. Personally I have many times used passive and active networks together. Here is a little trick. By using capacitors one can stack tweeters up on the same channel wired parralel and not worry about the impedance as long as there is one speaker that maintains the required load for the amp such as the woofer or midrange at say two ohms for instance. This can be very useful if you are trying to build say, a tweeter "array" that runs up the A-pillars for instance. This is something I have done in the past and it worked very well and sounded amazing. You start with two channels Front R-L. You put for example a third order high pass Butterworth x-over around 350 to 500 Hz on each channel with the active electronic or DSP unit and attach a 3 or 4 inch midrange in a pod or molded into the A-pillar trim at or about the base of each A-pillar with no passive network hooked to it. Then on the same channel you take a number of small tweeters, maybe four 1/2" to 3/4" fabric or metal dome tweeters and place them in a evenly spaced array up the A-pillar either in little pods or molded into the trim. Except with these tweeters each one will have a single 250 to 500 volt polypropylene foil capacitor that can very in value if desired. Say a 10uf at the bottom next to the midrange working up the array stopping with a 1uf cap on the one highest up on the A-pillar. As long as there is only a first order x-over consisting of a single capacitor on each tweeter and they are on the same channel with the 2ohm mid-woofer the amp will only see the 2 ohm load and you are free to stack tweeters and not send your amp into a conniption fit because it sees a short circuit due to the halfling of impedance you normally would see when wired in parallel without the caps. You can pad the tweeters down with resistors as long as they remain on the down stream side of the capacitors attached to the speaker terminals preferably.

[@MowSow]

You sir, speak on a completely different level. 90% of installers wouldn’t even understand half of what you just said. I love that. Do you have a site or page to follow your work ? Or a way to contact you for a question?

@@MowSow well thanks. Car audio has always been a hobby of mine. Pretty much every car I have ever owned I put a sound system in. Some of those systems where pretty elaborate. I don't install systems professionally but if you want to see something I am currently working on you can go to diyaudio forums and do a search for "My Tundra is getting a new system" and you will find my build thread for my 2019 Toyota Tundra. It is an on going project at this time. Nothing to over the top as I'm trying to maintain an OEM appearance and not destroy the resale value of my $60,000 truck by hacking apart all of the door panels and A-pillars .

I run my rear speakers off of my Kenwood deck. I have them crossed over (in the deck) at 100Hz 24dB/octave, and turned down as far as they can go. I don't really want to hear them, I just want to be able to tell something's not quite right if they weren't there at all. You don't sit with your back to the stage when you go to a concert, do you? That's why rear fill should barely be noticeable, if you even decide to use it at all. Deck power is perfect for this task. Head > DSP >4 channel active to mids and tweets, mono amp to subs.

[@MickeyMishra]

no one will argue that the engine is a very important thing in your car however you're also going to be wasting your money if you're rolling around on four Donuts. Mark is absolutely correct saying that a DSP is probably one of the best investments and one of the First Investments that you should make.. the audio control gear is top notch. it's one of those things where you buy it and you can just forget about it after that because you already know that part of your system is done there's nothing more to do and you don't have to second-guess your purchase or your decisions on your system. what I'm going to argue is that the rest of the components down the chain are so generic today that you can literally get by with just about anything and have an excellent sounding rig. the best part about going active as you no longer have to deal with the complexity of the crossover Dynamics and its interactions with the amplifier. You no longer have crossover Distortion because you don't have a crossover anymore. This is because of the nature of Class A /B amplification and something as completely sidestepped when you decide to go active. what this translates into is even some of the most modest budget amplifiers that you can buy at a Walmart can do the job with excellent results. the Jensen and the Dual amps , my personal favorite for Budget high quality sound. realistically the amplifiers audio control offers that have a built-in DSP are probably the best way to go since not only do you get a lower noise for you also get a easier system design. if you're not a basehead it's one perfect option. the one question I have is that I thought audiocontrol offered in at least previous versions of their professional Pro gear software and ability to control the high frequency mid-frequency and low frequency timings all on one channel . and professional installations you often have your woofers your mid-frequency drivers and your tweeters in far and different locations so even though they have built-in crossovers the actual devices themselves will be in different time placements and therefore will use a passive crossover in turn away but then use an active DSP to go ahead and take care of the time alignment and other needed functions such as frequency response characteristics of the event space to limit Reflections and Echoes and of course Peaks and they reproduce sound inside of the venue.. it gets a bit tricky with the passive crossover since you can make an adjustment however due to the analogue nature of the crossover you may have to deal then with phase issues and designing your slopes and your target timings in side of the DSP software can be a lot more challenging then simply going fully active. I want to make it clear that you don't need a DSP or Digital Signal processor but boy doesn't make life so much better. a lot of people are said that they don't care about Imaging until they actually listen to a system that was set up for it in the first place and they just can't go back after that. if you are truly on a budget and can deal with the very limited flexibility of the pioneer crossover unit that they offer that's a standalone then go that route the next best budget option is one of the Pioneers that have active mode capability. essentially it's the same thing as the DSP that's offered by pioneer, with a few features that make it worthy as an entry-level DSP to be used in the setups / scenarios that Mark is talking about. just my advice and take it for what you will, if you're going to go with audio control and you want a DSP get one that has the built-in amplifier not only is it a stellar value it really is a better way to go as far as a clean system install. glass RCA runs and a much cleaner signal coming out do the result of getting less interference since its in one nicely shielded chassis.

[@dannybartlett4225]

yes but a £1500 to £2000 head unit will have all this software inside and if you have passive crossovers they will not play slave to the head unit meaning the crossovers you install are doing zero nothing at all like having 2 of something doing noting ???

Thanks for this, this is exactly the question im asking my self with my upcoming install in my car! 👍

[@noecis37]

Hi Mark. What a great explanation. But what about a 3 way set with midbass, midrange and tweeter. Using a pasive crossover how would you time delay each driver? For example the 3 way focal flax evo has passive crossover and they are not bi-ampable.

[@andrea4809]

If the 3 way speakers are all mounted close to one another "and they should be" there is no need to delay them. you want to delay the speakers as a set. the goal is to delay the set of speakers that are closest to you vs the set on the other side of the car to create a center stage. You are wanting the sound from the left and the right to meet your ears at the same time, obviously the speakers in the drivers door are closer to you then the speakers in the passenger door therefore we delay the drivers speakers by just milliseconds behind the passenger door speakers as so the sound reaches you at the same time. Also don't mount mids in the doors and then mount the tweeters in the dash, they need to be close to one another.

[@dreednlb]

Wow, this is exactly the video I needed to see right now. My current amp's crossovers don't have a setting high enough for tweeters so I have passive crossovers. I'm also seriously considering upgrading to the D-5.1300.

[@jaimec2006]

Good info! So is still worth it if you have an amp that has Hi and Low bypass? Those DSP don't come cheap I rather not get one if my amp is already doing the same work.

[@brando81]

The amp isn't really doing the same work though. The high and low crossovers in your amp just widen or narrow the frequency sent to your speakers, whereas with a dsp you can boost/cut certain frequencies within that range. I would say it depends on your vehicle as well, in my new truck I would consider a more complete system, but in my jeep that I rip through the trails, new speakers on deck power is just fine.

[@MickeyMishra]

dude you don't need that much money to get good sound. get $109 Pioneer deck. best if you have an iPhone since you can stream high-quality audio right into the head unit. Francis vacation you can go to an AutoZone and pick up a dual 4 channel amplifier. the tweeters can be ran off of deck power just fine. Midbass will be going through the Dual amplifier and also through the subwoofer. you will just Bridges the last two channels to extract the most amount of power. the tweeters can be had for less than $8 a pair and they will perform really well they are available at your local junkyard and they usually stuff them in PT Cruisers and they have a made in Mexico label at the back of them they are a 4 ohm model and approximately 1 inch tweeter. on axis. they're one of the best sounding tweeters that you can get for practically nothing as long as you use a 24db crossover slope. your stock will first will do however if you seriously need to replace him this little baby a Parts Express for about 6 bucks should do the trick www.parts-express.com/6-1-2-Poly-Cone-Woofer-4-Ohm-299-609?gclid=Cj0KCQjwvr6EBhDOARIsAPpqUPFkEE9orYuc_J1oio2vuwVRJS-ynew-Y7jMBm5CNmz5BBxtTQAOyG0aArZ7EALw_wcB what you're really paying for with the higher-end components is more frequency extension and a clear presentation of the sound. However if you use the active settings on most pioneer decks you can actually get the sound quality of hire and parts but you'll have to do it by limiting the frequency range of your speakers. Your door speakers for example will probably be crossed over at about a hundred Hertz or 80 Hertz at 24dB. the killer songs here is that if you use the proper crossover points and run your speakers active you're actually able to make your system sound so much better even with stock components. you don't need a lot of money to get good sound you just need to get some free knowledge with people like me and others have been giving away for over 20 years. if you're willing? take the Venture into a junkyard and get some of these good parts from these cars and you can probably use them on your own or probably find stuff like this already installed them any vehicles and you get yourself a budget system. have a good one! iMickey503

Can I use an Active Crossover with a DSP?

[@billsmith5166]

Hmm. No, you wouldn't need an amp for each driver. A passive crossover is an attempt to make a channel's component speakers uniformly efficient. A crossover is also commonly designed to temper an audio signal from utilizing a bad sound characteristic from a component speaker. By using a crossover, theoretically, you will be trying to create a single, less distorted "multi-driver" rather than separate drivers in a channel that are each limited in their ability to recreate the entire audio spectrum. Thus, the crossover wants to make multiple drivers act like a single speaker, but it just can't. I don't think it's possible for a good crossover to be designed that will be successful in a car stereo environment because you can't uniformly apply corrections to multiple drivers in vastly different locations. That isn't to say that multiple drivers in a single location can't be "improved" by a simple crossover. Trying to do much more won't help much The use of a single amplifier channel driven to both a tweeter and midrange basically turns those separate drivers into a single speaker whether you want it to or not. You may not LIKE the result, but it can be vastly improved with the use of a good equalizer. You have thus created a "crossover" that should be able to remove the variation in the efficiency differences between the drivers with attenuation (exactly what happens with a crossover), and the peaks or valleys in the frequency response that would be created by driving them with a single channel of amplification can be smoothed. This is really only possible if you have an equalizer that has the ability to be adjusted for each channel. Many can't. You could use a separate equalizer for each channel, but this get's expensive. However, a good analog equalizer on each channel will do a better job than a typical car audio crossover can. In this case, they're both analog too. Thus, crossovers aren't required for car stereo and in most cases an analog equalizer can do more. A good DIGITAL equalizer will do EVEN BETTER than an ANALOG equalizer will. That's really as far as I can go. Even a little more depth requires a lot of typing and there aren't that many people that will read the comments anyway..

I'm not looking to spend a bunch of cash, but the Dodge has a factory system that I understand would only produce bass frequencies in the 6x9 door speakers that I would replace them with. So, what's the point in buying a 3 way coax? My question would be whether or not the stock infinity crossover in the factory system would still tell this Alipine passive crossover what frequencies to emit? Could I damage the Alpine 6x9 woofer by doing this, since it has its own passive crossover? I would not be using the tweeters that came with the Alpine SPJ691CS. I also thought about looking for an Infinity passive system to replace with instead of Alpine, as maybe this would communicate better being the same manufacturer? Perhaps I'll hook up the passive tweeters that come with the alpine in time, to replace corner dash tweeters, but not ready for all the mods yet. Thanks!

It's ridiculous the Audio Control DSP's don't have parametric EQ. It would be better to have 3 bands of parametric then 31 bands of graphic. I was shocked when researched car DSP's and found only a few have fully parametric.. Focal & JL Audio

[@brandonlejeune5820]

Power source? Still never got an answer!!

[@joearulappa2016]

I could be wrong but if you don’t have enough rca channels, can’t you use rca splitters

[@CarAudioFabrication]

Yes. But the signal will be exactly the same. So you lose the ability to now control every spear individually. Ideally every speaker has a channel, with the exception of subwoofers which typically have a Mono signal.

[@Hesbonful]

Hi Sir. Thank you so much for posting the video. Please advise. I can't get my subwoofer to produce 20Hz bass; it still has punchy bass, which I don't want. Should I use an aftermarket cross over like "boss" to get the 20Hz wavy bass? I have a 12 inch, 2000watt Pioneer sub in ported box (responsive to 20Hz) with a dedicated Pioneer mono block 1000Hz amp in my car. The remaining midranges and tweeters each have their own 6 channel pioneer amplifier. Finally, I have a graphic equalizer. Please advise, sir, if I should get a cross over I, and tune it to 20zHz ? I have tried using several graphic equalizers, but none of them had a 20Hz bass knob to enable this kind of bas.s P lease advise, Thanks.

[@LTZ_Z71]

This was seriously helpful.

[@jpmerrick8886]

If 3way pods from the midrange hmm

[@JamCityProsTV]

i would argue that using the 4 channel only on the components would sound better, since the rear speakers are generally only for "fill" ! So no need for the passive crossover . Run the 6x9 speakers off head unit power or cut them out until you can afford two more channels of amplification . never the less, great explanation of why someone may want to keep those power robbing passive crossovers

[@Me-dh4pm]

Audio control processors are very limited with graphic EQ only. So many other better options on the market. Do yourself a favor, Sell your passives and put the money towards proper amp channels.

[@dj_illeagle]

Do yourself a favor, finish your homework after doing a little more research youngin! Audio Control has never been about aesthetics, pretty lights and pretty colors are not what they are all about. High-level accurate tuning of high current competition systems is their niche!

[@Me-dh4pm]

@@dj_illeagle hmmm.... so your saying if I do more research what? People aren't using graphic processors in iasca and emma or other SQ comps. Helix,zappco etc. Are miles ahead with fully parametric capabilities, being able to assign differential inputs. You cant even disable the high pass on AC processors to get the max out of an IB setup. Explain your thought, what is better about Audio Control vs the 2 I mentioned? Are you saying because it's simple and limited that's a pro?

[@dj_illeagle]

Audio Control DM-608 and 810's use optical and in my option do there job better than the other big names you mentioned. Sure they're not petty to look at and even the software interface is nothing more than functional. But once properly set you can forget about it and let it do its job. Which it does very very well. Just one man's opinion. I think of it as the Diablo Sport of audio tuning without Trinity.

[@dj_illeagle]

@@Me-dh4pm It's only simply and limited to your use of the software. There's no good reason to overcomplicate the simple. Which is usually only done to sell product rather than increase any possible performance that's already hit the ceiling until the next audio tech advancement.

[@nrtg6290]

I really need help. I have JL C3 600. The passive crossover is 1st order on mid and 3rd order on the tweets. Through the Kenwood ddx395 crossover settings I run -12b on the front for -18db slope final Then -18db on rear speakers And -18db on the sub This puts the tweets at -30db (-18db passive plus the -12db sent to the fronts) how much tonal quality and I losing by doing this ? Running the fronts on through makes the fronts too muddy I'm running 80hz on sub lp and 120hz on fronts

[@davidjohnson5435]

I have a 2014 Kia Optima SX Turbo that I'm wanting to build a custom sub enclosure and amp rack in. I'll be using 10" PSI subs and the PSI 2500 watt amp. The sub requires a ported box 0.9-1.4 ft^3 between 30-36hz. How do I build a custom enclosure to them specs?

[@RawLobst3r]

This may not be the best video to ask on but figure maybe you’ll see this and have time. With the dm 810, or another DSP, could you run 2 x 5 channel amps (LC-5.1300), one 5 channel amp running the tweeters, rear doors, and 1 sub, and the other 5 channel amp bridged to 3 channels, running L/R mid bass and 1 more sub? I want to do this and am just trying to make sure my logic is sound before I order them, I’m mostly wondering about the sub configuration and if it could work as I’ve described, giving 500 watts to each woofer and either have 2 DSP channels for sub, or would I spilt one sub channel on the DSP output with a Y RCA. Thanks in advance if you see this!

[@brunom1280]

I have a mid Rande and a super tweeter connected together. Both 4 ohms. Trying to achieve 2 ohm load. Does a capacitor affect the final ohm load? I keep getting 3.8 ohms and cannot get a 2 ohm load unless capacitor is removed

[@cooljim2009]

I am upgrading the audio in my car adding a four channel amplifier to the head unit, a Subwoofer and a Set of Component Speakers for the front and Coaxial's for the Rear. I have a Ford Fiesta 2013. I have removed the front passenger door and see four wires going into a white plug then connects to the speaker harness. Rather than recycle this I am adding the new brackets and need to connect the four pin plug to the speaker. I found an adaptor specific to my car but only has two pins, so guessing the tweeters would not be connected. Also the tweeter is connected to a plug that clicks into the car door. The Component Speakers have built in Crossovers, however upon watching videos I discovered it would be so much easier to set it up with a Crossover as the two pin adaptor would connect directly to the crossover and the Sub and Tweeter directly to it with not need to solder wires or anything. My question therefore is this. Is it OK to add a passive crossover when the Component System has it built in?

[@Rugged_Peaks_Media]

I'm still curious to know should I still use my passive crossovers if I'm running a 6 channel amp with every speaker on its own channel with the d-6.1200 audio control amp

[@garyyoung824]

If using 3-way components up front, would you still treat the left and right fronts as channels 1 & 2 when using passive crossovers?

[@nicholaspayne349]

I was like yeah… I want that dsp. Looked it up and saw that it cost 750 bucks. That’s more than my entire system and the system in my wife’s car. Damn.

[@none3143]

As a hifi Enthusiast . Not. Audiophile because I'm not stupid. Yes it is pointless if you are using quality parts. You have just reminded me to actually dump my sonus Faber speakers and get a full range driver in an open baffle design. Thanks.

[@itsmeeeee3669]

if the 6.5 can take 200 rms and the tweeter 50 and i use a passive crossover rater for that power can i power them with 250 altogether just wonderin

[@rencechan5365]

Hi master. I have the same system with your setup in this video. I running a passive component (passive crossover w/2.5" full range & tweeter) real coaxial 2way 6.5". 1 x 10" underseat subwoofer. With a DSP (4in 8out build in 6chn amp) for front passive crossover point i used HPF 80hz 24slope, underseat sub LPF 50hz 24slope, real coaxial crossover set to off?

[@RinksRides]

BEST X-planation EVAR!

[@trey77]

Love your videos and have been a fan for a long time. How would I set up a system that has six speakers such as my Jeep Cherokee? It has front dash speakers running at 8 ohm and the front door and rear door speakers running at 4 ohms. My original thought was running the front dash speakers separate and having its own dedicated amplifier due to the low power they take to push them. Should I just use 8 ohm speakers for the dash since I am sure the power capacity will be lower than if they were running at 4 ohm vs. 8 ohm? I plan on running JBL speakers all the way through.

[@exploranator]

Actually, volume difference and sound character as modified by outer ear structure are the primary ways we determine directionality of a signal. The time difference being a significant factor in staging etc. is a myth. As an example, try a mono sound split into a stereo signal to two identical speakers and dial down the volume on one side or the other. What will happen is that the signal's point of origin, to your imagination, will shift toward the side with the louder sound. Your ears don't CARE which sound wave arrived first. They care about which is loudest, and the subtle modifications to the sound hitting your eardrums by the structure of your ears, which is why the ears have structure and shape, to help differentiate between front and rear.

I have a question for u im thanking of up grading my car system i have jbl gto 609c and was thanking of getting a jbl bass pro sl would i need another jbl amp to run my gto and could i connect them together i was just going to buy t amps but dont have the room so i need an under the seat sub thank u

[@saltdrum]

if i have passive crossovers and they are hooked up correctly, can i still blow my tweets by an adjustment i made on my radio?

[@koman4787]

Great video. Question: I just installed 2 12" alpine r12s, a fosgate 850.2 punch amp, a db drive neo 5 capacitor and a jl loc 22. It just doesn't give the punch. The gain is set to half but the interior factory speakers aren't loud like before and the voltage drops to 12.8 when the volume is on half. I've used fosgate 4awg ofc cable and knukonceptz rca

[@P00RKN00W]

I’ve noticed when using the smart DSP program for a while it starts acting up. Even when you try saving, for some reason it saves settings you never did or reverts them back to default until you restart the program. If you get lucky and get everything saved without hiccups, that 8x10 works wonders. I love the time alignment.

[@Hometheaterguyusa1]

Lose the rear fill-go all active.

[@nickorozco5933]

Hi, what if you have a built in EQ on the head unit? Would I just need to set the EQ flat or default setting before I tune DSP? Thanks 🙏

I have one question, how do adjust the sound for the tweeter and midrange on the dsp if they are on the same channel? Thanks your great!

Been watching your vids for awhile now, Thanks for the tips an companies you use. I just received my 1/0 ofc amp kit an wow what a difference!!!!

[@ragextico]

I hate being an over-thinker😔

[@roadtrippin2781]

If you don't need fade you can run the rear speakers on the same channels as the front then you can have the tweets on the unused channels, thus removing the need for anything passive.

[@beefy1978able]

I keep reading forums about noise floor issues with the DM 608 and DM 810 is this true or is it bad installs ?

[@beatmaniaboy]

Active crossover only you can finally get the correct acoustic response on both speakers and have both speakers arrive in Phase passive crossovers when you don't have enough channels

[@sibusisojele8805]

This video was very informative bravo. I have a question about the DSP if it's the same thing as an equaliser or active crossover?

Question about having a 6ch amp for the cabin speakers. That plus the other things with in the system. Is that the best way to get a true SQ system?

No wonder those modern car radios sound so good with all the sound processing in them

[@dattisha27]

if my system already has from stock a speaker and tweeter do i need to install a crossover when replacing speakers my car comes stock dsp

[@timmyl2005]

Love this Channel I have learned so much. You are a master of your craft Sir.

[@nic_indra]

I had a 2way full passive car audio system with DSP Amp. The DSP Amp only used for TA and EQ, so the DSP Amp doesn't work very hard.. got a great result and i'm very satisfied. Anyways, thanks for sharing Mark 👍🏻

[@MowSow]

So if the DSP Amp has also to filter frequencies there will be power supply issues and heat ? Vs letting the passive crossover for the component speakers do the filtering ? Is it a class D ?
